Method for producing window or door elements

Abstract

The invention relates to a method for producing window or door elements that have a profile frame made up of profile pieces, and that have at least one glass pane attached thereto. The profile pieces are pre-affixed to each other in order to form corner joints, and subsequently, the at least one glass pane is glued to the pre-affixed profile frame, so that the corner joints attain their stability from the glued-in glass pane.

1 . (canceled) 
     
     
         2 . The method according to  claim 16 , characterized in that, due to the glued-in glass pane, the corner joints have the stability needed for a window or door element and/or at least the same stability as conventional corner joints at a strength of at least 35 N/mm 2 , without a stabilizing glass pane. 
     
     
         3 . The method according to  claim 16 , characterized in that at least one of the corner joints—without the glued-in glass pane—has a stability that is lower than the stability required for a window or door element, and/or in that the corner joints have a strength of less than 35 N/mm 2 . 
     
     
         4 . The method according to  claim 16 , characterized in that the affixing is carried out in such a way that the profile sections are joined so as to be essentially liquid-tight. 
     
     
         5 . The method according to  claim 16 , characterized in that the profile pieces are affixed by welding. 
     
     
         6 . The method according to  claim 5 , characterized in that the profile sections each have a fusing addition that is less than 6 mm. 
     
     
         7 . The method according to  claim 16 , characterized in that the profile pieces are affixed by gluing. 
     
     
         8 . The method according to  claim 7 , characterized in that the profile frame and the glass pane are held in a fixed position for such a reaction time of the adhesive that the window or door element composed of the profile frame and the glass pane achieves sufficient stability to be handled. 
     
     
         9 . The method according to  claim 16 , characterized in that the profile pieces are selected from the group consisting of: weldable plastic profiles, polyvinyl chloride profiles, hollow profiles, hollow profiles made of metal, hollow profiles made of aluminum, and wood profiles. 
     
     
         10 . The method according to  claim 16 , characterized in that a hot-melt adhesive is used as the adhesive. 
     
     
         11 . A window or door element produced according to the method of  claim 16 . 
     
     
         12 . A window or door element comprising a profile frame made up of profile sections that have been pre-affixed to each other and to which a glued-in glass pane has been joined, whereby the pre-affixing has created corner joints that attain the stability required for a window or door element from the glued-in glass pane, or the corner joints attain at least the same stability as conventional corner joints from the glued-in glass pane, namely, a strength of at least 35 N/mm 2 , without a stabilizing glass pane. 
     
     
         13 . (canceled) 
     
     
         14 . The window or door element according to  claim 12 , characterized in that the corner joints are produced by welding the profile sections. 
     
     
         15 . The window or door element according to  claim 14 , characterized in that the profile frame is made up of profile sections that, before the welding, each have a fusing addition that is less than 6 mm. 
     
     
         16 . A method for making a window or door element, comprising:
 affixing two or more profile pieces to each other to form an individual corner joint of a profile frame;   forming the profile frame from multiple corner joints of affixed profile pieces; and   subsequently gluing with adhesive at least one glass pane to the profile frame to form the window or door element so that the corner joints attain stability from the glued-in glass pane.   
     
     
         17 . The method of  claim 16 , wherein the adhesive is a hot melt adhesive selected from the group consisting of: polyurethane based adhesives and polyolefin based adhesives. 
     
     
         18 . A method for shortening production cycle time for making a window or door element, comprising:
 pre-affixing two or more profile pieces to each other to form an individual corner joint of a profile frame;   forming the profile frame from multiple corner joints of pre-affixed profile pieces; and   joining a window pane to the profile frame to form the window or door element.   
     
     
         19 . The method of  claim 18 , wherein the profile pieces are comprised of plastic and are pre-affixed to each other by welding. 
     
     
         20 . The method of  claim 19 , wherein the profile pieces comprise a fusing addition that is in the range of about 1.5 mm to about 4.5 mm. 
     
     
         21 . The method of  claim 18 , wherein the profile pieces are comprised of wood and pre-affixing is without use of mortise and tenon joints. 
     
     
         22 . The method of  claim 18 , wherein the profile pieces are comprised of aluminum or other metal and pre-affixing is by tacking with one or more fasteners.
